To provide a mortar composition that does not easily droop when applied onto a slope and exhibits excellent freeze-thaw resistance and compression strength.SOLUTION: The mortar composition includes cement, a pozzolan material, rubber powder, and fine aggregate, with the content of the rubber powder being from 3 to 55 pts.mass relative to 100 pts.mass of the cement, the total content of the pozzolan material and the rubber powder being from 10 to 70 pts.mass relative to 100 pts.mass of the cement, and a ratio of the total mass of the pozzolan material and the rubber powder relative to the total mass of the pozzolan material, the rubber powder and the fine aggregate, ([total mass of the pozzolan material and the rubber powder]/[total mass of the pozzolan material, the rubber powder and the fine aggregate]) being from 0.03 to 0.23.SELECTED DRAWING: None
【課題】勾配部へ施工してもダレが生じにくく、且つ優れた凍結融解抵抗性及び圧縮強度を示すモルタル組成物を提供する。【解決手段】セメントと、ポゾラン物質と、ゴム粉末と、細骨材とを含み、ゴム粉末の含有量が、セメント１００質量部に対し、３～５５質量部であり、ポゾラン物質及びゴム粉末の合計の含有量が、セメント１００質量部に対し、１０～７０質量部であり、ポゾラン物質、ゴム粉末及び細骨材の合計質量に対するポゾラン物質及びゴム粉末の合計質量の比率（［ポゾラン物質及びゴム粉末の合計質量］／［ポゾラン物質、ゴム粉末及び細骨材の合計質量］）が０．０３～０．２３である、モルタル組成物。【選択図】なし
